Application filed m 16, 1911 5. Serial No. 40,241. a I

small individual glasses set in individual frames embedded in a concreteor cement slab.

nection with the accompanying drawing in which: i p V Figure l is a planof my improved vaultlight showing a group of the frames attached to eachother, two of the frames being shown in conjunction with the embeddingconcrete or cement, and one of these latter frames be ing shown as beingprovided with its glass: Fig. 2 a diametrical section, of one of theframes and its links, its glass appearing in elevation: Fig. 3 a sideelevation of one of the links employed in attaching the frames to eachother: and Fig. 4; a side elevation of an exemplifying tool which may beemployed in removing a damaged glass from its frame.

In the drawing :1, indicates a frame illustrated as being circular, as aIHBIB'GX ample of form, of a size to freely receive the glass to beemployed; 2, an upwardly prescnting shoulder on the interior of theframe at such distancebelow the top rim of the frame as corresponds withthe thickness of the glass; the glass, the same being of a form and sizeless than that of the interior of the top of the frame and adapted torest upon the shoulder 2 and fit the frame at its juncture with the,shoulder; 4, a perimetrical groove in the glass; 5, a groove formedwithin the interior of the frame o posite the groove 4; 6, perforatedears, illustrated as being four in number, projecting outwardly from theframe intermediate between the base and the top rim of the frame; 7,Wire links engaging the ears of the frame and adapted for connecting agroup of frames together, theselinks being preferably in the form ofstaples having their ends engaging the perforations in the ears of theframes and then bent inwardly to prevent their displacement from theears; 8.,the cement or concrete in which the frames are embedded;

My invention "will be readilytunderstood' from the following descriptiontaken in con-,

9, a tool well lending itself to employment,

-swi Pewter caries.

when a glass is to be removed from 1ts setting, this tool being in theform of a bar to serve as a handle; 10, a prong at one end of the toolto serve in removing the waterproof cement holdmg the glass in itssetting; 11, a prong at the opposite end of the.

tool to serve in catching in the groove-a of the glass; 12, a lugprojecting from the tool at the side opposite prong 11 and atsuchdistancefrom prong 11 that it may gage the depth of-penetration ofprong 11 into the space between the glass andthe frame; and 13,water-tight cement, of usual composition, disposed in the space betweenthe glass and that portionflof the inside of the frameoccupied by'theglass.

Gneof the frames with its glass is to be viewed as an individual unit,and these units may be associated, at such distance from each other asmay be desired, into a group embedded in the cement or concrete slab,the

tern as is desired and coupled together by the links. These links may beof such length as corresponds with the desired distance apart of theframes. The links may be inserted into the ears of the frames and theirends bent after the frames are disposed upon the supporting surface or,if desired, the frames may be associated and linked together and thenlaid upon the supporting surface. Thecement or concrete to form the slabis then to be placed around and be tween the frames and leveled OK, asby troweling, level with the top of the frames. \Vhen the material ofthe slab has set, it maybe removed from'the supporting surface andtransported and placed in its ultimate situation. The slab becomes areinforced structure by reason of the embedded frames and theirconnecting links. If the slabis to be constructed in the situation whichit is ultimately to occupy, then the p plane surface on which the slabis to be built may be formed by a suitably positioned andsupportingplatform. If the links are employed merely for posi tioningagents in securing proper relationship between the frames, the strengthof the i V links is immaterial so long as it will answer said purpose,but special reinforcing capacity will be derived, from the links if theybe of substantial size and material and are 1 clenched tightly to theears of the frames. The glasses are to be placed in the framesconcentric with the frames, the glasses centering themselves in theframes, and the iwater-p'roof cement applied around the Hglasses betweenthem and the interior of the frames. The glasses may be applied to.

the frames before the frames are set upon .the supporting surface in theprocess of forming the-slab, or the setting of the glasses in theframesmay be made the final element in the process of forming the slab. If a iglassbecomes broken andit be desired to re-' place it,'then-thewaterproof cement around the defective glass is dug out by means of thetool 9, the prong 10 being used for this purpose. The opposite end ofthe tool is now inserted into the space between the glass and frame, lugengaging the'top of the frame and determining when the. tool has beeninserted into the space a proper dis tance to bring prong 11 into theneighbor-- Goplesof this patent may be obtained for hood of groove 4 inthe glass. The tool is then used as a lever with lug 12resting on therim of the frame and the pried out of place. i

I claim 7 1. A vault-light comprising, a frame having an inward upwardlypresenting shoulder and an interior recess above said shoulder,

ears projecting from the exterior of the frame and adapted to receivelinks to connect the frame with similar frames, a glass glass lifted oradapted to rest upon said shoulder and have its upper surface flush withthe rim of the cars, a glass secured within each frame bysealing'material, links engaging Stud ears and uniting the frames, and aslab of plastic material embedding said ears and links and surroundingthe frames, combined substantially as set forth.
